Ask HN: Other websites using HN's forum software (news.arc)?

Someone mentioned TwoStopBits[1] in a comment[2] today, and I know there's the original Arc Language forum [3]. I remember seeing one other heavily modified one with a cool dark colourscheme, but I don't remember which.

Huh. I had no idea the design wasn't original. Thanks for posting this unintentional TIL!

It's pretty much original. Paul Graham made the Arc programming language, and the forum software / Hacker News on top of that.

Is the source code available for free use or is it a paid software offering?

Hacker News itself is closed source, but the old `news.arc` code is available under the Artistic License 2.0.
